My thoughts on the Big Pump are using a PWM scheme, anything below
x amount of TPS, or x MAP, and it goes on.  Really early in the timing of
events so as to have time to be up to speed, for big demand.  Popular
Electronics had a Motor Speed Contoller Article within the last 2 years
that gave some details about freq for the PWM, and used a couple 555
to run a Power MOSFET, which could be ganged for big outputs.
